HiPOD: Impact by Impact

Situated next to a much larger and older crater, this candidate impact site formed at most between August 2016 and April 2020. From Context Camera data, there is a large dark blast zone in a follow-up image that was not present in an earlier one. Other images might have been acquired that narrow this range but were unavailable to the CTX team at the time this target suggestion was created.

HiRISE 3D: Mounds on a Crater Floor

This Target is meant to document a sample of the cone and dome shaped landforms on this crater floor.

HiPOD 31 Aug 23: Well-Preserved in Nereidum Montes

Also visible in Context Camera data, this observation gives us a high-resolution view of a sharp-rimmed, gullied crater with bedrock exposures and intricate ejecta flow patterns. Nereidum Montes is an over 1,100-kilometer length range of mountains northeast of Argyre Planitia.

NASA officials sound alarm over future of the Deep Space Network - https://arstechnica.com/space/2023/08/nasas-artemis-i-mission-nearly-broke-the-deep-space-network/

The electronics unit for CCD RED4 started to fail in August 2023, and we have not been acquiring images in this central swath of the images. The processing pipelines will be updated to fill this gap with the IR10 image for some products. The 3-color coverage is now reduced in width.

HiRISE Instrument News:

Since July 23, 2023, HiRISE observations have lacked data from the RED4 CCD due to a hardware issue, creating a gap in the middle of image products and reducing the color swath to 1 CCD width. We are investigating the hardware issue and may be able to acquire some RED4 data in the future.

@Kittiekatt53 Contraction and expansion of ground ice is the hypothesis.

Not sure why the word scientists is put in quotes, but, okay.

HiRISE 3D: A Spooky Crater

There are lots of secondary craters in this area that are well preserved, yet the main crater is extremely shallow, probably due to relaxation in ice-rich ground .

HiPOD 30 Aug 23: A Layered Sequence in Terby Crater

The western face of this bench has one of the best exposures of layered deposits in Terby Crater. The sequence consists of 4 sub-units within the 2.5 km-thick sequence. This location has many angular unconformities that are not exposed in the same sequence further south. This image will help determine the nature of the deposit and the possible correlation of layers in the same bench to the south.

HiRISE 3D: Valleys in a Crater near Mawrth Vallis

There are valleys in this crater that terminate at the central pit. Were they formed through fluvial processes?

HiPOD 29 Aug 23: Dipping Layers in Centauri Montes

The objective of this observation is to examine some sets of dipping layers along a mesa in Centauri Montes. Pictures like this will help us determine the horizontal extent of these features which are supposed to be the remains of an ice-rich unit that was widespread in the past.

HiPOD: A Possible Clay-Rich Deposit

The nearby Nirgal Vallis locale exposes a clay unit in its valley walls. This observation aims to determine if this unit can be determined elsewhere in the region, such as in excavations in nearby craters. This crater likely has nice bedrock exposures, as visible in THEMIS and Context Camera data, and an overlapping CRISM image indicates a clay exposure.

HiRISE 3D: Crevasse-Like Features

This request was made to obtain a stereo pair for an eventual digital terrain model, and to see if any changes occurred since a previous image.

HiPOD 24 Aug 23: Boulders inside of Pits

The objective of this observation is to determine the nature of boulders sitting inside of pits along the edge of a mesa. Wind may have blown away the material around the boulders. This image will also include exposed layers in the mesa wall and gives us more examples of these features from a previous HiRISE image at a nearby location.

HiPOD 23 Aug 23: HiPOD: A Scarp in Pavonis Mons

HiRISE images of other steep-sided edifices within the Pavonis Mons fan-shaped deposit are providing new insight into volcano-ice interactions that occurred as the deposit formed. Context Camera images reveal several shapes not commonly visible in the other images; more detail would be helpful in distinguishing between hypotheses for the development of this plateau.

HiPOD 22 Aug 23: Candidate Lake Deposits

In this observation, we want to take a look at candidate lake deposits fed by alluvial fans. High resolution will help us to check for layers, layer tilts, to test this lacustrine hypothesis. Tilts more than approximately 2 degrees suggest not lacustrine, but rather distal alluvial origins.
